Diet plays a surprisingly large role in the health of your feline. Genetics play a role in disease, but what your cat eats, or doesn't eat, can influence overall health in major ways. Over the past seventy years or so, highly processed and carb-laden foods have become the norm for feeding cats. During this time, the incidence of many feline diseases such as diabetes, irritable bowel disease, kidney and urinary tract disease and dental disease have increased dramatically. We don't think this is a coincidence.
A bio-appropriate raw meat diet can have a profound effect on the health of cats with these diseases. A proper diet can also influence whether a cat gets sick in the first place. In diabetes, low or no-carbohydrate raw diets can dramatically reduce or eliminate the need for insulin injections. Many cats with IBD that are put on raw diets show relief from symptoms, as do cats with urinary tract problems. Chewing on whole raw meats and raw meaty bones keeps teeth clean and gums healthy, reducing the chances of periodontal disease.
Think of a tiger. People naturally think of big cats eating raw meat. It's an image that comes easily to mind. Too often though, when people think of a housecat's meal, they think dry kibble. Cats are cats. We are doing our feline family members a disservice when we forget that they are highly evolved predators, especially adapted to a diet of raw flesh. Forgetting that simple truth has allowed us to stray very far from what our companion cats should be eating, with significant health consequences for our feline family members.
Feline Diabetes: The Influence of Diet
Feline diabetes mellitus is similar to human type II diabetes, also known as non-insulin dependent diabetes. In these patients, the pancreas is able to produce insulin, though it is not enough to adequately control blood sugar. This may be due to damage from inflammation of the pancreas, overwork and exhaustion of the pancreas due to chronically elevated blood sugar and/or if the cells of the body have become somewhat resistant to insulin. Whatever the cause or causes, the end result is the insulin produced by the pancreas is no longer enough to control blood sugar.¹ Continued
Feline Inflammatory Bowel Disease: Nature and Treatment
The inflammatory bowel diseases are the most common cause of chronic vomiting and diarrhoea in cats, and refer to a group of diseases. The term Inflammatory Bowel Disease, or IBD, is applied to a group of poorly understood gut pathologies that are considered to be a consequence of uncontrolled intestinal inflammation in response to a combination of elusive factors that may involve the diet, the environment, the gut microflora and dysregulation of the immune system in susceptible cats. Continued
Feline Hyperthyroidism: What You Need to Know
Hyperthyroidism, or thyrotoxicosis, is the most common endocrine disease in cats. When an animal or a person has hyperthyroidism it means that there is a high concentration of thyroid hormones in the blood. The opposite, low thyroid hormone levels, is called hypothyroidism. Hyperthyroidism occurs mostly in older cats, generally around 12 years old, although reports have shown a wide range between 4 and 23 years.¹ There is no predisposition related to sex or breed. Continued
High Blood Pressure: Yes, Your Cat Can Get It, Too
Hypertension is the medical term for high blood pressure, which is a common problem in older cats. In cats, hypertension is commonly found as a complication of other underlying medical conditions, so-called secondary hypertension. However, primary or essential hypertension, i.e., hypertension that develops without any underlying medical disorder, may also be seen in cats. In contrast to people, where essential hypertension is most common, secondary hypertension is more common in cats. Continued
Feeding for Urinary and Kidney Health
There is a connection between what cats are fed and what diseases they might get. This is an idea that is becoming much more widely accepted. Diet plays a role in disease syndromes such as kidney disease, urinary problems such as stones and crystals, Feline Lower Urinary Tract Disease and gastrointestinal problems such as IBD. The kidneys regulate the water and salt balance in the body, maintaining hydration, electrolyte levels and regulating blood pressure. As proteins are metabolized by the body for energy, by-products are produced and circulated in the blood. It's the kidney's job to remove these toxic substances. Continued
Constipation: Real Help for Your Cat
One of the immediate results when feeding a raw meat diet is less cat poop, and cat poop that smells less. While some cat owners welcome this change, some are concerned that their cats might be constipated. Feeding a raw diet can closely resemble nutritionally what cats would eat if living wild in their native habitat, but, despite our best efforts, it is not a truly natural diet. The natural diet can only be replicated by feeding small whole prey. One of the biggest differences between feeding raw diets and the natural prey diet is fur. Continued
Water, Water and Water Battles Crystals
My 4 year old kitty, Roxy, had 5-6 crystallite stones in her bladder that were removed in January of this year. She has been on a raw diet ever since, exclusively. I have noticed, though, that her water intake has gone to zero since starting the raw diet. I have been adding 6-8 teaspoons of water to her raw food every serving to make up for it. She has been tested four times since her surgery, x-rays and urine draw from the bladder with no crystals showing up.
So, we are one year out from Roxy having had calcium oxalate stones removed and so far no recurrences. Good job. Continued
Feline Cystitis and Bladder/Kidney Stones
Cystitis and stones are extremely common in the cat and can be very painful and life-threatening. Cystitis can lead to inappropriate urination – urinating outside of the litter box – and stones can cause a fatal rupture of the bladder by blocking the outflow of urine.
Any cat that is repeatedly entering the litter box but not voiding any urine is in need of immediate medical attention. It is important to note, however, that "crystals" are not the same thing as stones. Continued
Nutrition is Vital for FeLV Cats
The feline leukemia virus, generally referred to as FeLV, is classified by virologists as a retrovirus. A retrovirus uses an enzyme called reverse transcriptase to insert copies of its own genetic material into the cells it has infected in order to produce a new copy of a whole virus. Infected cats can be found everywhere, but the prevalence varies depending on many factors: age, health, reproductive status, concurrent disease, environment, lifestyle, etc. The worldwide prevalence is about 5% of free-roaming cats. Continued
Feline Pancreatitis: Signs of Trouble
Pancreatitis can be a frustrating disease in cats. The cause often can't be definitively determined and the symptoms can be vague. Pancreatitis can range from low-grade with mild symptoms to severe, which can be fatal. Most often, treatment is supportive, alleviating symptoms and keeping the cat comfortable.
The pancreas is a lobulated gland located along a portion of the small intestine in mammals. The pancreas has two types of tissue, each one of them synthesizing a different type of secretion. Continued
 Raw Food Essentials and Fun Stuff, Too!
The Feline Nutrition Foundation is dedicated to educating people about the benefits of feeding their cats the right kind of diet. We want science-backed information to be freely available to everyone. That's a core part of our mission. We emphasize the freely part. Membership is free, all the information we offer is free and we don't have ads cluttering up the site. Everyone associated with our education and advocacy work is a volunteer. We are passionate about helping cats. But, passion doesn't pay the bills. Continued
Another Furball? It Might Be Feline Asthma
Has your cat been coughing? Watch the video below and you may recognize that sound. Many people assume that the cat is trying to cough up a hairball and don't realize that their cat could have asthma. Untreated, asthma can progress and even be fatal. But, like human asthmatics, cats can be treated and the disease can be managed.
It is estimated that about 1% of cats suffer from asthma.¹ Siamese, Burmese and other Oriental breeds show a greater incidence, but any breed can have asthma.² Continued
 Bio-Inappropriate: The Dangers of Dry Food
I have never seen a single case of serious obesity, diabetes, urinary tract disease, or IBD in a cat fed meat instead of commercial dry foods. Many other people have seen the same results.
Further, I do not see nutritional deficiencies in cats fed properly balanced raw-meat diets. I want to emphasize a point here. The incidence of these problems has not just declined on a raw-meat diet, they have entirely disappeared. These results are too dramatic to ignore. Continued
 Chunks and Bones For Your Cat's Teeth
Knowing that chewing on meat chunks and small pieces with bones, such as chicken wings, are "nature's toothbrush" for cats, I want my cat to eat these to help clean her teeth. But, she refuses to eat meat chunks no matter what I try. Someone told me this could be because her teeth hurt. She has some tartar on her teeth. Could this be why she won't eat chunks?
Domestic cats are strict carnivores. They evolved to hunt, ingest and efficiently digest small prey. They have developed very specific taste and scent capabilities that prevent them from consuming anything that is not fresh. Continued
Food Allergies and Intolerances Explained
My cat almost always vomits after I feed her anything with beef in it. When I mentioned to a friend that I thought he was allergic to beef, she corrected me and said that vomiting was a sign of food intolerance, not a food allergy. Now I'm confused. What's the difference between the two? If they are two different things, what are the signs to look for in each case?
Food allergy is a specific type of reaction by the body to an allergen, usually a protein in the food. It is defined as "an adverse reaction to a food or food additive with a proven immunologic basis."¹ Continued
Avoiding Hepatic Lipidosis in Your Cat
I'm transitioning my reluctant kitties to a raw diet and a few times they have refused to eat the new food. I always end up giving them something else since I have read all of the warnings about cats going without food for too long and getting hepatic lipidosis.
How dangerous is it for a cat to go without eating? What should I look out for?
Hepatic lipidosis, also called fatty liver disease, may be the most common disease of the liver of the cat. It occurs when there is an excessive accumulation of fat inside the cells and tissues of the liver. Continued
Get Kitty Exercising to Trim Down
Do cats need to exercise? My cat is overweight. Would exercising help him to lose weight like people? If so, what should I get him to do and for how long? I never think of cats doing anything for an extended period of time, just short bursts of activity, like running, chasing or climbing. Is it known how many calories a cat burns chasing a toy for ten minutes?
The short answer to the question is yes, cats do need exercise. We can conclude this because, while their digestive physiology may be unique, the cardiovascular physiology of cats appears to be similar to other mammals, such as humans. Continued
Salmonella: The Chicken or the Egg
Are raw eggs safe to feed to your cat? You may be wondering after hearing about eggs being contaminated with salmonella. Eggs are a great food source for cats. Raw egg yolks are a good source of protein, folate, vitamin B12, omega-3 and omega-6 fatty acids. Eggs are also a good source of the antioxidant lutein. Egg whites are an excellent source of phosphorus-free protein for those cats that need a phosphorus reduced diet. Egg whites should be served cooked, as raw egg white can interfere with biotin absorption.¹ Continued
Safe Handling Practices for Raw Meat
One of the major concerns of people feeding a raw diet is safe food handling to protect the human family and our companion animals. Knowing the difference between spoilage and pathogenic bacteria as well as following temperature and time guidelines makes our decision to feed a raw diet easier. Much of the information provided in this article is directed at human safety – a standard also used by many people when feeding their companion animals. This information is from the Food Safety and Inspection Service of the USDA and other sites that rely on USDA and FDA guidelines. Continued
If You're Feeling Stressed, So Is Your Cat
We live in challenging times and external stressors abound. The economy, the news and often just getting through the day all present a source of stress for people. It's known that owning a pet has beneficial effects on our health.¹ Pets help us slow down. We get so caught up in the business of our daily lives that we rarely take enough time to stop and take a break. Studies have shown that even a few minutes of petting your cat or dog can lower your blood pressure and release endorphins that put you in a better mood.² Continued
Diabetes and Obesity: Preventable Epidemics
Today, the cat is the favorite house pet in the United States, at least if your definition of "favorite" is "most numerous." The cat has outnumbered the dog, the previously "most numerous" pet species, for a decade or more and this trend shows no signs of reversing itself anytime soon. Those of us involved in any of the pet care industries or professions know very well that we are seeing more and more well-cared-for felines, belonging to people and families that are intensely bonded to their kitty family members. Continued
Case Examples of Tight Regulation of Diabetes
Real life examples show the crucial role diet plays in treating feline diabetes, and the devastating effect dry food carbohydrates can have on cats. Maggie is a 10-year-old female white long-haired cat. Like almost all of my patients, she had eaten dry food since she was a kitten. Occasionally her owners would feed her some canned food as a special treat, but during the day she ate many small meals of a "premium quality" dry cat food. She had been healthy for 10 years and was not overweight at 8 pounds. Continued
Choosing the Right Insulin for Diabetes
My cat was diagnosed with steroid induced-diabetes. For the past three years, he's been on Depo-Medrol® injections every three months or so for IBD. Could his diabetes be reversed? He always ate mostly raw and Katz-N-Flocken® dry. I am now weaning him to Wysong Epigen® with no carbs. He was just diagnosed and started on NPH insulin. Should I insist on PZI?
First, I'd like to address the issue of treating inflammatory bowel disease with Depo-Medrol® injections. Depo-Medrol® is an injectable repository form of very potent corticosteroid. Continued
An Appropriate Diet for a Diabetic Cat
Feline diabetes is not the natural fate of hundreds of thousands of pet cats world-wide. It is, rather, a human-created disease that is reaching epidemic proportions because of the highly artificial foods that we have been feeding our feline companions for the past few decades. Without the constant feeding of highly processed, high carbohydrate dry foods, better suited to cattle than cats, adult-onset feline diabetes would be a rare disease, if it occurred at all. One of the questions that diabetic cat owners ask most frequently is, "what should I feed my cat?" Continued
A Veterinarian's View: Andrea Tasi, VMD
My name is Andrea Tasi, and my whole life revolves around cats and cat care. I graduated from the University of Pennsylvania School of Veterinary Medicine in 1988 and was determined to go out into the world and help sick cats get better, and keep well cats well. I have been in feline exclusive practice since 1991, first in Philadelphia and now in the Washington, D.C. metropolitan area. I have watched cats become the most popular pet in our country, and been part of the evolution of feline specific veterinary medicine. Continued
